The SanDisk microSD Express Card (SDSQXFN-256G-GN4NN) is a high-performance storage solution officially licensed for the Nintendo Switch 2. By utilizing a PCIe-NVMe interface, it achieves read speeds of up to 880 MB/s and write speeds reaching 650 MB/s, which significantly reduces loading times for large game files compared to traditional cards. It also maintains a sustained write speed of 210 MB/s and carries U3 and C10 speed class ratings to ensure stable data recording. Despite its advanced internals, the card retains the standard microSD form factor and is backward compatible with UHS-I and UHS-II devices, allowing you to move your 256 GB of storage capacity between different hardware. To handle the heat generated by these high speeds, SanDisk integrated ThermaAdapt technology, which helps regulate temperature during intense gaming sessions. This card comes with the official Nintendo Seal, making it a reliable choice for gamers who want to expand their console's capacity to 256 GB without compromising on speed.
